REGISTRATION RIGHTS

Section 2.01 Shelf Registration.

(a) Shelf Registration Statement

(i) The Corporation shall (A) if it is a Well-Known Seasoned Issuer, prepare and file an Automatic Shelf Registration Statement on or as soon as reasonably practicable (but no more than two business days) following the expiration of the Lock-Up Period (as defined herein) with respect to any Registrable Securities, or (B) if it is not a Well-Known Seasoned Issuer, prepare and file a Registration Statement on or before the 45th day following the date of this Agreement, and shall use its commercially reasonable efforts to make such Registration Statement effective as soon as reasonably practicable thereafter, and in any event no later than the date that is three months after the date hereof. In no event may the resales by the Selling Holders take the form of an underwritten offering of Registrable Securities without the prior written agreement of the Corporation.

3

(ii) If a Registration Statement is required to be filed pursuant to Section 2.01(a)(i), the Corporation will use its commercially reasonable efforts to cause the Registration Statement filed pursuant to Section 2.01(a)(i) to be continuously effective under the Securities Act, with respect to any Holder, until the the date on which there are no longer any Registrable Securities outstanding (the “Effectiveness Period”). The Registration Statement when declared effective (including the documents incorporated therein by reference) shall comply as to form in all material respects with the applicable requirements of the Securities Act and the Exchange Act and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (and, in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, the Corporation shall provide the Holders with written notice of the effectiveness of the Registration Statement.

(b) Delay Rights. Notwithstanding anything to the contrary contained herein, the Corporation may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement, suspend such Selling Holder’s use of any prospectus that is a part of such Registration Statement (in which event the Selling Holder shall suspend sales of the Registrable Securities pursuant to such Registration Statement) if (i) the Corporation is pursuing an acquisition, merger, reorganization, disposition, or other similar transaction and the Corporation determines in good faith that the Corporation’s ability to pursue or consummate such a transaction would be materially and adversely affected by any required disclosure of such transaction in such Registration Statement, (ii) the Corporation determines it must amend or supplement the Registration Statement or the related prospectus so that such Registration Statement or prospectus does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading, (iii) the Corporation would be required to disclose material information or the Corporation has experienced some other material non-public event, in each case the disclosure of which at such time, in the good faith determination of the Corporation, would materially and adversely affect the Corporation; provided, however, that in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to such Registration Statement for a period that exceeds an aggregate of sixty (60) days in any 180-day period or ninety (90) days in any 365-day period. The Corporation shall use its reasonable best efforts to limit any delay pursuant to the foregoing to as short a period as is practicable, and upon disclosure of such information or the termination of the condition described above, the Corporation shall provide prompt notice to the Selling Holders whose Registrable Securities are included in such Registration Statement, shall promptly terminate any suspension of the use of any prospectus that is a part of such Registration Statement it has put into effect, and shall take such other actions necessary or appropriate to permit registered sales of Registrable Securities as contemplated in this Agreement.

Section 2.02 Further Obligations. In connection with its obligations under this Article II, the Corporation will:

4

(a) promptly prepare and file with the Commission the Registration Statement and such amendments and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities covered by such Registration Statement;

(b) furnish to each Selling Holder (i) as soon as reasonably practicable before filing the Registration Statement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the Commission), and provide each Selling Holder the opportunity to object to and comment on any information pertaining to such Selling Holder and the plan of distribution that is contained therein and make the corrections reasonably requested with respect to such information prior to filing such Registration Statement and the prospectus included therein or any supplement or amendment thereto, and (ii) such number of copies of such Registration Statement and the prospectus included therein and any supplements and amendments thereto as such Selling Holder may reasonably request in order to facilitate the resale or other disposition of the Registrable Securities covered by such Registration Statement;

(c) if applicable, use its commercially reasonable efforts to promptly register or qualify the Registrable Securities covered by the Registration Statement under the securities or blue sky laws of such jurisdictions as the Selling Holders shall reasonably request; provided, however, that the Corporation will not be required to qualify generally to transact business in any jurisdiction in which it is not then required to so qualify or to take any action that would subject it to general service of process in any such jurisdiction in which it is not then so subject;

(d) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any such Selling Holder under the Securities Act, of (i) the filing of the Registration Statement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Registration Statement or any post-effective amendment thereto, when the same has become effective; and (ii) the receipt of any written comments from the Commission with respect to any filing referred to in clause (i) and any written request by the Commission for amendments or supplements to such Registration Statement or any prospectus or prospectus supplement thereto;

(e) promptly notify each Selling Holder, at any time when a prospectus relating thereto is required to be delivered by any such Selling Holder under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained therein, in the light of the circumstances under which a statement is made); (ii) the issuance or express threat of issuance by the Commission of any stop order suspending the

5

effectiveness of the Registration Statement or the initiation of any proceedings for that purpose; or (iii) the receipt by the Corporation of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, the Corporation agrees to, as promptly as practicable, amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing and to take such other action as is reasonably necessary to remove a stop order, suspension, threat thereof, or proceedings related thereto;

(f) upon request and subject to appropriate confidentiality obligations, furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the Commission or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(g) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission;

(h) use its commercially reasonable efforts to cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by the Corporation are then listed;

(l) if reasonably required by the Corporation’s transfer agent, the Corporation shall promptly deliver any authorizations, certificates, opinions and directions required by

6

the transfer agent, including the release of any stop transfer orders, to authorize and direct the transfer agent to transfer Registrable Securities without legend upon sale by the Holder of such Registrable Securities under the Registration Statement or an available exemption from registration with the Commission.

Each Selling Holder, upon receipt of notice from the Corporation of the happening of any event of the kind described in Section 2.02(e), shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 2.02(e) or until it is advised in writing by the Corporation that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Corporation, such Selling Holder will deliver to the Corporation (at the Corporation’s expense) all copies in its possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

Section 2.03 Cooperation by Holders. The Corporation shall have no obligation to include Registrable Securities of a Holder in the Registration Statement if such Holder has failed to timely furnish such information that the Corporation reasonably determines, after consultation with its counsel, is required in order for the Registration Statement or prospectus supplement, as applicable, to comply with the Securities Act.

Section 2.04 Lock-Up Period. Each Holder agrees that, during the period beginning on the date of this Agreement and ending 180 days thereafter (the “Lock-Up Period”), such Holder will not offer, sell, contract to sell, pledge, grant any option to purchase, lend or otherwise dispose of the Registrable Securities issued to such Holder pursuant to the Purchase Agreement; provided, however, that the Lock-Up (as defined below) shall expire in respect of 20% of the Holder’s Registrable Securities if for ten consecutive trading days beginning on the date that is three months after the date of this Agreement and prior to the expiration of the Lock-Up Period, the closing price of the Corporation’s Common Stock exceeds by 20% or more the price of the Corporation’s Common Stock at the date of this Agreement (“Lock-Up”); provided further, that nothing herein shall prohibit or otherwise prevent or restrict any transfer during the Lock-Up Period from one Holder to another Holder or from any Holder to one or more of its Affiliates.

Section 2.05 Expenses. All Registration Expenses shall be borne by the Corporation. In addition, for the avoidance of doubt, the Corporation shall pay its internal expenses in connection with the performance of or compliance with this Agreement (including all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed. All Selling Expenses relating to Registrable Securities registered shall be borne by the Holders of such Registrable Securities.

Section 2.06 Indemnification

(a) By the Corporation. In the event of the Registration of any Registrable Securities under the Securities Act pursuant to this Agreement, the Corporation will

7

indemnify and hold harmless each Selling Holder thereunder and each Person who participates as an underwriter in the offering or sale of Registrable Securities (if customarily required), and their respective directors, officers, managers, partners, employees and agents and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act, and its directors, officers, managers, partners, employees or agents (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses, or liabilities (including reasonable attorneys’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder Indemnified Person may become subject under the Securities Act, the Exchange Act, or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact (in the case of any prospectus, in light of the circumstances under which such statement is made) contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the Registration Statement, any preliminary prospectus, prospectus supplement, or final prospectus contained therein, or any amendment or supplement thereof, or any free writing prospectus relating thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading or (iii) any violation by the Corporation of any federal, state or common law rule or regulation applicable to the Corporation and relating to action or inaction by the Corporation in connection with any such Registration of Registrable Securities, and in each case will reimburse each such Selling Holder Indemnified Person for any reasonable, documented legal or other expenses incurred by such Selling Holder Indemnified Person in connection with investigating, defending, or resolving any such Loss or actions or proceedings; provided, however, that the Corporation will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in conformity with information furnished to it by such Selling Holder Indemnified Person in writing specifically for use in the Registration Statement or prospectus supplement, as applicable. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder Indemnified Person, and shall survive the transfer of such securities by such Selling Holder.

(b) By Each Selling Holder. Each Selling Holder severally and not jointly agrees to indemnify and hold harmless the Corporation and its directors, officers, employees, and agents and each Person who, directly or indirectly, controls the Corporation within the meaning of the Securities Act or of the Exchange Act to the same extent as the foregoing indemnity from the Corporation to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Registration Statement, any preliminary prospectus, prospectus supplement, or final prospectus contained therein, or any amendment or supplement thereto or any free writing prospectus relating thereto; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds received by such Selling Holders from the sale of the Registrable Securities giving rise to such indemnification.

8

(c) Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but the omission to so notify the indemnifying party shall not relieve it from any liability that it may have to any indemnified party other than under this Section 2.06(c), except to the extent that the indemnifying party is materially prejudiced by such failure. In any action brought against any indemnified party, it shall notify the indemnifying party of the commencement thereof. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.06 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof, other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense or employ counsel reasonably satisfactory to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of such separate counsel and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnifying party shall settle any action brought against any indemnified party with respect to which such indemnified party may be entitled to indemnification hereunder without the consent of the indemnified party, unless the settlement thereof imposes no liability or obligation on, includes a complete and unconditional release from liability of, and does not contain any admission of wrongdoing by, the indemnified party.

(d) Contribution. If the indemnification provided for in this Section 2.06 is held by a court or government agency of competent jurisdiction to be unavailable to any indemnified party or is insufficient to hold such indemnified party harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that the liability of each Selling Holder shall not be greater than the maximum amount for which such Selling Holder could have been liable under the proviso contained in Section 2.06(b). The relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative

9

intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to herein. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating, defending, or resolving any Loss that is the subject of this paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e) Other Indemnification. The provisions of this Section 2.06 shall be in addition to any other rights to indemnification or contribution that an indemnified party may have pursuant to law, equity, contract, or otherwise and shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any indemnified party and shall survive the delivery of and the payment for any Registrable Securities sold by any Holder.

Section 2.07 No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any Holder to sell any Registrable Securities pursuant to any effective registration statement.

Section 2.08 Exchange Act Compliance. If the Corporation is subject to the requirements of Section 13 or 15(d) of the Exchange Act, then the Corporation shall timely file all reports required to be filed by it under the Exchange Act and it will take such further action as any Holder may reasonably request so as to enable each such Holder to sell the shares of Common Stock of the Corporation that it holds without registration under the Securities Act pursuant to Rule 144 under the Securities Act, as such rule may be in effect from time-to-time, or any similar or successor rule or regulation hereafter promulgated by the SEC.
